ramsc: You had forgotten to include the US government among the hackers' group. Conceivably, outfits like the CIA, NSA and computer literate gurus in the military industrial complex are overly busy right now hacking into Middle Eastern countries' server infrastructures. Obviously Al-Jazeera's website was manipulated too in an attempt to mask the photos of dead US soldiers.
Planting bugs or attacking servers in one region can easily spread viruses into adjacent regions.
Perhaps the attack on Pprune which was said to have originated in Taiwan had originated from the bowels of the National Security Agency, or the FBI? Maybe somebody had said something in a forum which was of a sensitive intelligence nature; or perhaps suspected terrorists could be using the Pprune forums and message services to communicate in code?
Who knows for sure? And what can you do?
